ISAAC B. INGLE, OF BLOOMINGTON, ILLINOIS.

WIND OW-VENTILATOR.

Application filed June 30, 1915.

To all whom t may concern Be it known that I, ISAAC B. INGLE, a citizen of the United States, residing at Bloomington, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Vindow-Ventilators, of which the following is a specification.

This invention relates to window ventilators, and one of its objects is to provide a ventilator attachment for the window sashes of houses, railway passenger coaches, etc., which will permit free ventilation to any degree desired without opening the sash, and which will prevent the entrance of dust, cinders and other foreign substances.

A further object of the invention is to provide a window ventilator which may be adjusted to regulate the admission of air to the interior of the room or car, which is designed effectually to prevent draft arising from sudden gusts of air passing into the room or car, and which embodies means for further regulating the aggregate size of the 'air inlet to govern the volume of air admitted into the apartment.

A still further object of the invention is to provide a ventilator which is proof against the entrance of rain or snow, which permits of the ready drainage oi' of all moisture, and which may be applied or embodied with equal facility in old or new windows.

The invention consists in the features of construction, combination and arrangement of parts hereinafter more fully described and claimed, reference being had to the accompanying drawings, wherein- Y Figure 1 is a vertical front-to-rear section through a portion of a window frame and the lower sash, showing the 4invention applied and embodied in the sash as part there-y of; Fig. 2 is a sectional planview through the part shown in Fig. 1, the plane of section being on a line above the ventilator and showing the lid or cover of the ventilator casing thrown open; Fig. 3 is a view similar to Fig. 2, showing the lid or door of the ventilator casing closed; Fig. 4'is a view similar to Fig. 1, showing the ventilator in the form of an attachment to the lower sash; Fig. 5 is an exterior elevational view of the sash and ventilator shown in Fig. 4.

Referring more particularly to Figs. 1 to; 3, of the drawings, 1 designates a window;

struction, and 2 the lower' sash, which, when in closed position is adapted to rest against the base or sill 3 of the window frame. A s shown in these views, the ventilator forms a part of the base or bottom rail of the sash 2 and includes a box or casing 4 extending horizontally across the base of the sash, upon the inner side thereof, and having in the form shown a hinged lid or cover 5 provided with one or more air inlets or ventilation openings 6, preferably covered by screen gauze 7 in order to prevent the admission of dust, cinders and other foreign particles.

The lid may be dispensed with and a rigid 'f1 top substituted therefor, but when a lid is employed the said lid is provided with a suitable knob or finger piece 8 whereby it may be conveniently opened and closed. l/Vhen the lid is closed, the amount of air admitted is governed entirely by the aggregate area of the inlets 6, but if the admission of a greater volume of air be desired the lid may be thrown back to an open position, thus entirely uncovering the opening at the top of the casing for the admission of air. Fixed to the top of the lid or cover is a flanged metallic frame 9 having upstanding portions 10 forming guideways for one or, more sliding dampers or cover plates 11 which may be adjusted to restrict the size of the inlets 6 to decrease the amount of air admitted to the room or apartment or to out off entirely the entrance of air as desired. The guideways formed b v this metallic strip have end portions 12 which serve as guards and prevent the removal of the sliding dampers 11, thus preventing their detachment by children or malicious persons.

The outer side of the casing is formed by the bottom rail 13 of the sash, as part thereof, which rail may, therefore, be made of somewhat greater depth or vertical extent than is usual. rl`he rail is provided with a longitudinally extending opening 14, which is of a length substantially equivalent to the casing 4 and provides for the free admission of air to the interior of said casing. As shown, the bottom 15 of the casing is in` clined or sloped outwardly and downwardly to permit of the drainage off of all moisture, while the upper wall of the opening 14l is beveled or inclined upwardly and inwardly,

i. as indicated at 16, t`o increase the size of the opening 14 inwardly of its entrance, thus allowing air freely to pass to the top of the casing, while at the same time diminishing Yventilation of the the size of the entrance side of the opening 14 in such a manner as to prevent snow from being blown into the casing and through .the V inlets 6 into the car and lodging in and choking up the casing. The beveled surface 1G furthermore gradually restricts the size of the passage leading from the opening 14 to the inlet G, thus preventing sudden drafts of air from passing through the inlets into the room or apartment.

It will be evident from the foregoing description that as the ventilator forms a part of the base of the sash,'the sash may be kept entirely closed, while at the same time free roomor apartment through the sash may be permitted in such a way as to protect Y the occupants of the room from dust, cinders, dirt, snow, rain and drafts, and ample ventilation may be obtained without the necessity of opening the window, and while the window may be heldY fastened or locked in closed position, as during the night time. In order to govern. the supply of air through the ventilator, and further diminish the liability of the forcible entrance of air, I provide an adjustable damper 17 in the flaring passage leading to the inlets G. Thisv damper preferably consists of a block of wood or other suitable material, of triangular form in cross section, and having pins or reduced portions 18 at its ends to pivotally and removably engage grooves 19 in the end walls of the casing' 4, 1 whereby the damper block is pivotally and removably mounted. The block may be turned to different positions, so as -to present its base or broad side either upwardly or downwardly to vary the size of the passage. If at any time it should be desired to secure the fullest ventilation possible, the block may be removed by simply sliding it upward out of the grooves and as readily replaced again for use by simply fitting it down into the grooves, as will be readily understood.

In:` the form of my invention shown in Figs. 4 and 5, the construction of the lventilator casing and base board or bottom rail 13 is the same as the board or rail 13 previously described, except that instead of forming a part of the bottom rail 20 of the sash 2 it is arranged beneath the bottom rail 4ofthe sash and secured thereto byssuitable fastening brackets E21.v The constructionof the ventilator is otherwise the same as that previously described. In both constructions, it will be evident that the ventilator comprises a base board or rail having an admission opening of the character defined therein, and a casing upon the inner side of the board or rail constructed and operating as described, whereby the device is adapted to be built in as a part of the base or sash or may be applied as an attachment to a sash already inl use, in which latterevent a portion of the sash rail may or mayV not be cut oli', as desired.

One advantage of my invention is that the ventilator may be built in to form the lower portion of the sash, by simply disposing the lower cross bar of the sash at an elevation between the side bars of the sash, and then disposing the ventilator in position between the lower extensions of the side bars thus produced. The upper portion ofthe sash may then be closed in the usual way, while the lower portion provides aventilator, and this sash may be of any stock size and adaptedto be opened and closed'and fastened in the usual way.
